Description

Technical Field

[0001] This utility model belongs to the field of pipeline cleaning technology, and in particular relates to a pipeline cleaning device for water conservancy projects. Background Technology

[0002] After prolonged use, water pipes accumulate scale and debris on their inner walls, increasing the risk of blockages.

[0003] According to the search, CN221609070U discloses a cleaning device for drainage pipes. When moving and cleaning the pipe, the cleaner needs to be manually adjusted to keep it in contact with the inner wall of the pipe. The cleaner rotates inside the pipe, which can easily cause the device to shift. It is difficult to maintain the coaxiality between the device and the pipe, which can easily cause errors and affect the stability of the device's movement and cleaning inside the pipe. It can also easily damage the movable connection structure that connects to the cleaning brush. Utility Model Content

[0004] The technical problem to be solved by this invention is to keep the device coaxial with the pipe, so that the cleaning brush fits against the inner wall of the pipe, thereby improving the stability of the movement and cleaning process.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a water conservancy engineering pipeline cleaning device, comprising a rotating rod, a connecting plate, a support frame, a centering adjustment component, and a cleaning component. The connecting plate is fixedly connected to both ends of the rotating rod through the support frame. The support frame is symmetrically distributed around the rotating rod and is rotatably connected to the rotating rod. The centering adjustment component is movably connected to the end of the connecting plate away from the support frame to keep the rotating rod coaxial with the pipeline. The cleaning component is slidably disposed inside the rotating rod through the side wall. A rotary motor is installed inside one side of the support frame, and the output end of the rotary motor is fixedly connected to one end of the rotating rod.

[0006] Furthermore, the cleaning components are arranged in a spiral pattern along the axial direction of the rotating rod.

[0007] Furthermore, the centering adjustment assembly includes a screw, a movable disk, a slide rod, a sliding sleeve, and a support wheel. One end of the screw is rotatably connected to the center of the end face of the connecting plate away from the support frame. A handle is fixedly connected to the end of the screw away from the connecting plate. The movable disk is sleeved on the outer wall of the screw and threadedly connected to the screw. The outer wall of the sliding sleeve is hinged to the end point of the side wall of the connecting plate. One end of the slide rod is hinged to the outer circumference of the movable disk. The other end of the slide rod passes through the sliding sleeve and slides inside the sleeve. The support wheel is rotatably connected to the outer wall of the other end of the slide rod.

[0008] Furthermore, the sliding sleeves are arranged at uniform intervals around the screw, and the positions of the sliding rod, sliding sleeves, and support wheel correspond to each other.

[0009] Furthermore, the cleaning assembly includes a connecting rod, a stop block, a cleaning brush, and a support spring. The connecting rod is slidably disposed inside the rotating rod through the side wall of the rotating rod. The stop block is fixedly connected to one end of the connecting rod. The cleaning brush is fixedly connected to the other end of the connecting rod. The support spring is wrapped around the outer side wall of the connecting rod and is located between the cleaning brush and the rotating rod.

[0010] Furthermore, the fixed angle of the cleaning brush is set in a deflected manner.

[0011] With the above structure, the beneficial effects of this utility model are as follows: For cleaning the inner wall of water conservancy pipelines, the centering adjustment component support device is movably connected to the connecting plates at both ends of the rotating rod, keeping it coaxial with the pipeline. The support wheel is adjusted by sliding the equal-length sliding rod in the sliding sleeve, and the support wheel supports the inner wall of the pipeline, stabilizing the movement of the device. The rotating rod is located at the center of the pipeline, and the rotating motor drives the rotating rod to rotate, so that multiple cleaning components sequentially fit against the inner wall of the pipeline and clean the inner wall of the pipeline. Keeping the rotating rod coaxial with the pipeline increases the stability of the device when cleaning the pipeline. Attached Figure Description

[0018] like Figure 1-4As shown, a water conservancy project pipeline cleaning device includes a rotating rod, connecting plates, support frames, a centering adjustment component, and cleaning components. The connecting plates are fixedly connected to both ends of the rotating rod via the support frames. The support frames are symmetrically distributed around the rotating rod and are rotatably connected to the rotating rod. The centering adjustment component is movably connected to the end of the connecting plate away from the support frames to keep the rotating rod coaxial with the pipeline. The cleaning components slide through the side wall of the rotating rod and are installed inside the rotating rod. A rotary motor is installed inside one side of the support frame, and the output end of the rotary motor is fixedly connected to one end of the rotating rod. The rotating rod is rotatably connected to the connecting plates at both ends via the support frames. The symmetrical support frames are supported on the inner wall of the pipeline by the centering adjustment components to keep the rotating rod coaxial with the pipeline. When the rotary motor drives the rotating rod to rotate, the rotating rod drives multiple cleaning components to rotate and clean the inner wall of the pipeline.

[0019] like Figure 1-4 As shown, to improve the stability of the device, maintain the coaxiality of the rotating rod with the pipe, and enable positioning inside pipes of different diameters, the centering adjustment assembly includes a screw, a moving disc, a sliding rod, a sliding sleeve, and a support wheel. One end of the screw is rotatably connected to the center of the end face of the connecting plate away from the support frame. A handle is fixedly connected to the end of the screw away from the connecting plate. The moving disc is sleeved on the outer wall of the screw and threadedly connected to the screw. The outer wall of the sliding sleeve is hinged to the end of the side wall of the connecting plate. One end of the sliding rod is hinged to the outer circumference of the moving disc, and the other end of the sliding rod passes through the sliding sleeve and slides on the sleeve. Inside the pipe, the support wheel is rotatably connected to the outer wall of the other end of the slide rod. The sliding sleeves are evenly spaced around the screw rod. The positions of the slide rod, sliding sleeves, and support wheel are corresponding. Symmetrical centering adjustment components support the rotating rod at both ends. Turning the handle clockwise moves the moving disc along the axial direction of the screw rod, while simultaneously pushing the slide rod to move. The slide rod slides inside the sliding sleeve, causing the support wheel to move towards one end of the rotating rod. The angle between the slide rod and the connecting plate decreases, and the support wheel extends outward. Multiple support wheels fit against the inner wall of the pipe, keeping the rotating rod in a centered position and achieving coaxial positioning of the rotating rod and the pipe.

[0020] like Figure 1 and Figure 3 As shown, in order to avoid the device shifting when the supporting force of the cleaning component is concentrated in contact with the inner wall of the pipe, and to make the cleaning component contact the inner wall of the pipe from multiple angles, thereby improving the stability of the device during the cleaning process, the cleaning component is arranged in a spiral shape along the axis of the rotating rod.

[0021] To achieve the cleaning brush adhering to the pipe wall, the cleaning assembly includes a connecting rod, a stop block, a cleaning brush, and a support spring. The connecting rod slides through the side wall of the rotating rod and is located inside the rotating rod. The stop block is fixedly connected to one end of the connecting rod, and the cleaning brush is fixedly connected to the other end of the connecting rod. The support spring is wrapped around the outer side wall of the connecting rod and is located between the cleaning brush and the rotating rod. The connecting rod passes through the rotating rod and slides inside the rotating rod. The support spring supports the cleaning brush, allowing the cleaning brush to automatically adhere to the inner wall of the pipe. When the cleaning brush encounters resistance, it can slide along the axial direction of the connecting rod.

[0022] The cleaning brush is fixed at an angle with a deflection. The cleaning brush uses its tilted side to contact impurities inside the pipe, reducing the rotational resistance of the cleaning brush and enabling it to move the internal cleaning fluid or water.

[0023] In actual use, in the initial state, the centering adjustment component is in the storage state, the moving plate is close to the handle, and the angle between the slide rod and the connecting plate is the largest.

[0024] Adjust using the centering adjustment components at both ends. Turn the handle clockwise to move the moving disc closer to the connecting plate along the axis of the screw, while simultaneously pushing the slide rod to move. The slide rod slides inside the sliding sleeve, causing the support wheel to move towards one end of the rotating rod. The angle between the slide rod and the connecting plate decreases, and the support wheel extends outward. Multiple support wheels fit against the inner wall of the pipe, keeping the rotating rod in the center position and achieving coaxial positioning of the rotating rod and the pipe.

[0025] Simultaneously, a rotary motor is driven to rotate, which in turn drives a rotating rod to rotate, causing multiple cleaning components to rotate and clean against the inner wall of the pipe. This allows the cleaning components to contact the inner wall of the pipe from multiple angles, improving the stability of the device during the cleaning process. A support spring supports the cleaning brush, allowing it to automatically conform to the inner wall of the pipe. When the cleaning brush encounters resistance, it can slide along the axial direction of the connecting rod. The cleaning brush uses its inclined side to contact impurities inside the pipe, reducing the rotational resistance of the cleaning brush and enabling it to move the internal cleaning fluid or water.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents. In conclusion, if those skilled in the art, inspired by this description, design similar structural methods and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
